Inventor: YAMAMOTO SANEHIRO
IPC: C08F255/04
Filed: 1988-04-18
Abstract: PURPOSE:To obtain the title elastomer improved in heat resistance, oil resistance, methanol resistance, water repellency, oil repellency, cost, etc., by grafting a specified fluorinated olefin compound onto a polyolefin elastomer.

Title: Intake device for internal combustion engine
Inventor: NOMOTO YOSHITAKA
IPC: F02B29/08
Filed: 1986-04-23
Abstract: PURPOSE:To obtain high leveled charging efficiency of intake, by setting the opening of a valve in its valve opening initial period to a small time change rate, in case of the control valve provided in an intake passage in the upstream of intake ports. CONSTITUTION:A control valve 10, which is provided in an intake passage 3 in the upstream of intake ports 16, is actuated such that the control valve opens after the top dead center of suction to delay the intake start timing. A pressure inverting part 21, which is provided in the intake passage 3 in the upstream side from the control valve 10, inverts an intake negative pressure, generated in the downstream side of the control valve 10, when it is opened. The above described control valve 10 sets the opening in its valve opening initial period to a smaller time change rate than that in the valve opening intermediate period or final period. In this way, since an inertia intake pulsation, generated in a preceding cylinder side, is suppressed as much as possible from being damped, high leveled charging efficiency of intake is obtained.

Title: Air conditioner for vehicle
Inventor: NIIKURA YASUHIRO
IPC: B60H1/32
Filed: 1982-06-02
Abstract: PURPOSE:To reduce the energy consumed a compressor and damp any shock applied to a vehicle by a method wherein each of a plurality of compressors is turned on or off in response to a thermal load so as to increase or decrease the number of operating compressors. CONSTITUTION:In case of cooling-down operation, two units of compressor are operated. When an appropriate cooling limit temperature TL, is obtained only one compressor is operated. When a temperature rises up to an appropriate cooling upper limit temperature TH, two compressors are operated to control the temperature between the upper and lower limit temperatures. When the temperature drops below TL and reaches TLcheck, one compressor in operation is stopped and restarted when the temperature TL is recovered. Thus, when the temperature rises up to THcheck one more compressor is put in operation the compressor is turned on or off step by step in response to the temperature in compartment room of the vehicle, thereby the energy consumed in the compressor can be reduced, the size of the compressor can be decreased and its shock can be damped.

Title: Humidity detector
Inventor: SAKATA KEIKI
IPC: G01N27/04
Filed: 1983-05-30
Abstract: PURPOSE:To detect changes in the humidity from variations in the resistance component by drawing only the potential cleared of effect ascribed to the capacity on a timing pulse synchronizing a square wave from the output of a humidity sensor. CONSTITUTION:A square wave generation circuit 2 receives a voltage v1 and generates a square wave 2 of the frequency determined by the time constant gamma1 =C1R5 and values of resistances R3 and R6. The voltage v3 gives a saw-tooth waveform only during the voltage v2 according to the time constant gamma2=C2R8. When the voltage v3 becomes larger than the voltage v1 (the time length T), the output v4 of a comparator 3 moves to a high level (Vc). Due to the effect of the capacity portion CHD of a humidity sensor HD, the voltage v5 at the positive terminal of an amplifier 4 varies as illustrated. Thus, when the voltage is drawn immediately before the square wave rises or falls, the resistance component RHD of the humidity sensor can be detected as DC voltage v6, which enables a rough setting of the frequency for the square wave free from changes in an external power source affecting the performance and characteristics to facilitate the adjustment of circuits.

Title: Magnetic recording and reproducing device
Inventor: SAITO TOSHIYA
IPC: G11B5/027
Filed: 1985-05-07
Abstract: PURPOSE:To execute a reproduction by a good S/N by varying a turn ratio of the primary side and the secondary side coils of an input transformer, in accordance with an output per one turn of a head of a magnetic recording medium to be reproduced, and always fetching a reproducing signal of the same level from the secondary side of the input transformer. CONSTITUTION:When a magnetic head 1 moves on a magnetic recording medium, a reproducing signal is induced in a coil 2, and this reproducing signal is inputted to a primary side coil 31 of an input transformer 3. Accordingly, when the reproducing signal flows to the primary side coil 31, a reproducing signal having a voltage level corresponding to the respective numbers of turns is induced in secondary side coils 32, 33. In case when an output per one turn of a head of the magnetic recording medium is large, a movable terminal (c) of switches 4, 5 is switched in advance to a terminal (a) side by a head switching signal 100, and in case when the output is small, the movable terminal (c) is switched in advance to a terminal (b) side. A booster ratio of the input transformer 3 is determined by the primary side coil 31 and the secondary side coil 32 or 33. Therefore, an input level of a reproducing signal processing circuit 6 always becomes roughly constant.

Abstract: PURPOSE:To automatically obtain the optimum picture quality in accordance with the level of a reproduced FM video signal by using an envelope curve detecting circuit for reproduced FM video signal and controlling a picture quality control circuit in response to the output of the envelope curve detecting circuit for control of the picture quality. CONSTITUTION:An envelope curve detecting circuit 3 varies the output voltage in response to the level of a reproduced FM video signal.

In such a way, the video signals of optimum picture quality are always obtained from the circuit 2 in response to the S/N of the FM video signal.

Abstract: PURPOSE:To reduce the power consumption and to prevent the deterioration or damage of an integrated circuit by providing the 3rd transistor acting as a current source in series with a level shift circuit in the level shift circuit having the 1st and 2nd MOS transistors (TRs). CONSTITUTION:The level shift circuit consists of a current limit NMOS (M7), an NMOS (M6) acting as a switch while receiving a signal A, and a PMOS (M5) deciding a voltage of an output node (b) of the level shift circuit. When a TR M6 is turned on with the signal A at the power supply potential V1 and the voltage current characteristic is as shown in Curve 3, but the characteristic of the M7 has a capability flowing only the current I1 as shown in Curve 2. The synthesized current characteristic by the TRs M6, M7 shows a characteristic shown in Curve 2, where I2 is the current capability when the TRM6 is turned on and the relation of I1<<I2 exists, and the current source is regarded as that having the current capability I1. Thus, even when the power supply voltage V1 is fluctuated remarkably, the TR group connected to a power supply voltage V2 is neither deteriorated nor damaged.

Filed: 1980-07-15
Abstract: PURPOSE:To keep the dynamic balance of a rotary body including a rotor for a rotary magnetic head in a final package state automatically with high precision, by providing a dynamic balancing mechanism at one end of the rotor in its rotary shaft direction. CONSTITUTION:At one end in the rotary shaft direction, a rotor 11 for a rotary magnetic head is equipped with a dynamic balancing mechanism consisting of an external ring 7 for an annular steel-ball guide track, an internal ring 8 for the annular steel-ball guide track, and several steel balls 9 held in a groove formed between the external fing 7 and internal ring 8.

This constitution eliminates the need for the mechanical addition and reduction of the mass, and keeps the high-precision balance automatically in the final package state.
